—Co-located collaboration in classroom is the topic we tackle in this paper. We present COFFEE a tailorable collaborative environment that is designed for interactive, colocated (i.e. Face2Face) collaboration in classroom. We present the requirements for tailorability that have driven our design, COFFEE architecture, some tools that have been deployed and discuss the latecomer management issue that is offered by the core of our architecture to all the tools that can be developed within the framework.
